Abstract

The invention provides a method for optimizing performance parameters of a movement mechanism of electronic equipment, which comprises the following steps: performing three-dimensional modeling on theelectronic equipment; respectively establishing a multi-rigid-body dynamic model and a rigid-flexible coupling multi-body model based on the established three-dimensional model of the electronic equipment; adopting a virtual prototype method to obtain the dynamic errors of the models; and optimizing the performance parameters of the movement mechanism of the electronic equipment by taking the minimum dynamic error as a target. Based on a multi-body dynamics method, the method respectively establishes the multi-rigid-body dynamic model and the rigid-flexible coupling multi-body model, optimizes to obtain the structural parameters of the high-precision and high-speed electronic equipment by taking the systemic dynamic accuracy as a target. The method has the advantages of accuracy, convenience, practicability and the like, contribution to improving the design capacity, acquisition of a better product structure and the like.

Description

technical field [0001] The invention belongs to the field of industrial equipment, and in particular relates to a method for optimizing performance parameters of a motion mechanism of electronic equipment. Background technique [0002] Optimal design is a new modern design method, which aims to improve product quality and reduce product cost. [0003] At present, the realization of high-speed and high-precision electronic equipment is completed by CNC control, system mechanical structure, feed drive and other auxiliary parts such as chip removal system and cooling system device. Among them, the matching selection of key structural parameters such as the connection stiffness and damping of the slider, the torsional stiffness and torsional damping of the coupling, and the connection stiffness and damping of the nut seat have a great influence on the dynamic accuracy of the system. [0004] For the optimal matching of various structural parameters in the design of high-precisi...
